In a mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until well combined.
In a separate bowl, combine the milk, egg yolk, vegetable oil, and vanilla extract. Whisk until the mixture is smooth.
Pour the wet mixture into the dry ingredients. Stir gently until just combined.
Place your non-stick skillet over medium heat and add a small pat of butter to grease the pan.
Pour the batter into the skillet, forming a round pancake. Cook for about 2-3 minutes, or until bubbles form on the surface.
Carefully flip the pancake using your spatula and cook for another 1-2 minutes, until golden brown.
Transfer your pancake to a plate, add a pat of butter on top, and drizzle with syrup.
